This platinum bracelet contains 31 antique-cut Burmese rubies totaling 60 carats and was designed by Harry Winston, Inc. It was an anonymous gift to the Natural History Museum in 1961. There isn’t much information in their catalogue about the corundum (var. ruby) on the left except that it was mined in Myanmar (Burma).

One person had asked if these gems are replicas. They aren’t – they’re the real thing, part of the museum’s priceless gem collection. Some people may remember a gem exhibit I photographed at the Hillwood Estate, jewels previously owned by heiress Marjorie Merriweather Post. She had donated many of her pieces to the Smithsonian, and this is where they’re normally displayed.
